针对230″经编机压电贾卡梳栉数控铣削加工误差产生的主要原因,分析了该类超长细薄零件数控铣削加工过程中涉及到的工艺路线、走刀策略、工件装夹及切削参数等对加工质量的影响,提出了减小贾卡梳栉的数控铣削加工变形,提高其加工精度和表面质量的工艺措施。实验结果表明,采用该文提出的贾卡梳栉铣削工艺,零件的加工精度及表面粗糙度均达到了使用要求。

Based on the main factors resulting in NC milling errors of piezo-jacquard guide bar used on 230＂ warp knitting machine,the NC milling techniques of long and thin workpieces affecting machining quality in the manufac- ture process,such as machining path,cutting strategy, fixing workpieces and cutting parameters were analyzed. The techniques and technological ways of controlling deformation and improving milling precision and surface quality were proposed. The results showed that the milling precision and the surface quality requirement was reached be- cause of the milling technique of piezo-jacquard guide bar.
